I find it ironic that you should mention Britain. Other than 9/11 and other attempts since 9/11, Britain and Japan are the only two countries on the planet which have attacked the USA and Britain did it twice. Why are they our supposed ‘friends’?
Don’t say Mexico because Texas was not a state when Mexico attacked a then possession of Mexico.
Both Britain and Japan are countries which should be our bitter, untrustworthy enemies.
Yes, Chinese hate Japanese because they remember the Nanjing massacre and I do not blame the Chinese. The Japanese showed their brutality not only to Nanjing residents but to our troops, too, a la “The Bataan Death March”.
However, we do all have our opinions. ;-)
That policy provided some guidance to the United States, resulting in keeping their emperor out of a nuclear blast.
I was answering the question "Why didn't we nuke Tokyo?", not designating our closest friends.
